SWITCH-STAND.

SPECIFICATION forming part of Letters ratent No. 669. 1 dated MarchApplication filed December 6, 1900. Serial No. 38,873. (No model-) T061/ whom it may concern.-

Be it known that I, JOHN WRIGLEY, a citizen of the United States,residing in Elmira, in the county of Ohemung and State of New York, haveinvented certain new and useful Improvements in Switch-Stands; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use thesame, reference being had to theaccompanying drawings, and to the reference characters marked thereon,which'form a part of this specification.

This invention relates to railroad-switchoperating mechanism, and it hasreference particularly to that class of switch-operating mechanism whichis used most commonly in controlling sidings, being operated by aweighted hand-lever adapted to be thrown over to either of two positionsto open or close the switch, as the case may be.

The object of the invention is to provide a mechanism of this naturewhich shall be simple and compact in construction, positive and easy inoperation, proof against becoming clogged in the connections between itsmoving parts by water freezing upon them, and capable, in having itsparts arranged so as to be interchangeable and reversible, of readyadaptation to either side of the road-bed.

The invention consists in the improved railroad-switch-operatingmechanism constructed substantially as will be hereinafter particularlydescribed, and finally embodied in the clauses of the claim.

In the accompanying drawings, Figure 1 is a plan view of arailroad-switch andof my improved switch-operating mechanism. Fig. 2 isa view in end elevation of said switchoperating mechanism, a portionthereof being removed. Fig. 3 is a side view of the invention. Fig. disa horizontal sectional view on the line m m in Fig. 2. Fig. 5 is a viewin end elevation, partly in section, of a modified form of theinvention; and Figs. 6, 7, 8, and 9 are plan views of several differentforms of one of the parts of the mechanism.

In said drawings, a designates the main rails and b the switch-points,the latter being connected in the usual manner by rods 0.

f designates a detector-bar which is pivotally secured to the free endsof links g, that are in turn pivoted on clips 7t, secured to one of therails. The detectorbar serves the usual purpose of preventing thethrowing of the switch while the train is partly on and partly off thesame.

i denotes my improved switch-operating mechanism, thesame beingpreferably secured upon the end of one of the ties adjacent the switch.

I prefer to inclose the working parts of the mechanism as much aspossible, so as to protect them against disarrangement by accident orfrom being clogged by snow or ice produced by water freezing upon them,and for this purpose I provide a casing j, which affords a support forsaid working parts. Said casing is preferably rectangular in form andcomprises two sections is Z, the section It being adapted to restimmediately on the tie or other suitable support, while the section Zrests on said section 76, being provided with a top or cover portion 'm.The two sections are secured together by means of bolts n, which engagecorresponding integral projections 0 of said sections and which in theirmiddle portions are formed in semicylindrical shape, as at 19, so as toproduce a hearing between each two such corresponding cylindricalportions for a trunnion q. The section 76 is adapted to be secured tothe tie by spikes in the usual manner, integral flanges r, havingspike-openings 3, being formed at the base of said section on twoopposite sides thereof for this purpose. There are two of the trunnionsq, the same forming longitudinal extensions of a cylinder 25, saidcylinder being inclosed within the casing and having a cam-slot u formedspirally therein..

1; denotes a lever, which comprisesa sleeve portion 20 and two armportions 00, one of said arm portions projecting from one end and theother from the other end of said sleeve portion on opposite sidesthereof. Said sleeve portion of the lever has trunnions y, which arejournaled in integral inwardly-extending projections z of the twosections of the casing. One of the arms w of said lever is provided witha pin 1, which engages the slot u in the cylinder, while the other arm mprojects through a horizontal opening 2 formed in the casing. .In orderto thoroughly protect the mechanism Within the casing, I provide theupper section thereof with a downwardly-extending lip 3, which overlapsthe joint-line between the two sections onthree sides of the casing. Onthe fourth side, since it would be impracticable to associate the partsif the opening 2 for the lever-arm were in the form of an orifice in oneof the sections and in order at the same time to preserve the joint armof the lever, so as to Work therewith.

The slide may be disposed either on the inside or the outside of thecasing of course. The outer arm 00 of the lever 12 carries a pin 8, towhich is pivotally secured the free end of the rod 9, which connects theswitch-points with said lever.

10 is an integral arm, which projects from the upper casing-section landwhich is formed with a vertical sleeve portion 11, which providesbearings for a spindle 12, that is sustained against downward movementin the sleeve by a collar 13, which rests upon the top of the sleeve.This spindle may carry at its upper end a target, lamp, or othersignaling device 13, while its lower end is provided with a crank 14;,having a slot 15, which receives the pin 8. Thus as the lever 01 isshifted the motion is transmitted to the signaling device as well as tothe switch-points, both being set simultaneously. Each trunnion qprotrudes from its bearings. One of these trunnions carries a crank 16,which is removably secu red thereto by a pin 17, which penetrates thecrank and fits in a cross-cut 18 in the trunnion. This crank and thedetector-bar are pivotally connected by a rod 19. The other trunnioncarries an arm 20, which is removably secured thereto in the same manneras is the crank 16 to its trunnion, said arm being adapted for turningthe cylinder to operate the mechanism and being provided, as usual, witha weight 21.

It will be of course understood that either or both of the extremitiesof the slot to in the cylinder 25 may be so formed that for a shortdistance the slot will extend at right angles relatively to the axis ofthe cylinder, so that when the pin of the lever is engaging this portionof the slot the mechanism will be positively locked against operationexcept by turning the cylinder. The drawings Figs. 4, 6, 7, 8, and 9show cylinders having various forms of slots.

In the use of that form of the cylinder which is illustrated in Figs. 4and 9, where both exthe wheels of a train can move the switchpoints somepart of the mechanism must be broken, and before even a manual operationof the cylinder can be effected the entire train must clear thedetector-bar.

In the modified form of my invention shown in Fig. 5 instead ofproviding a lever v of the shape of that already referred to I employ astraight lever 22, fulcruming the same upon a vertical stud 23 of anintegral projection 24; extending inwardly from one of the walls of thecasing-section 70. In other particulars this form of my invention issubstantially like that already described.

It is preferable that the flanges r be provided on each side of thefulcrum of the arm 20 with a stop 25 upon which said arm may rest as itis thrown-over from oneposition to the other, for without this thecylinder would soon have such arange of movement that the pin would beengaging the end of the slot to theinjury of the mechanism, as when, forinstance, the arm had nothing to take against afiording more substantialresistance-than the tie or the road-bed.

By arranging the several parts in the manner which I have abovedescribed they are made so that the mechanism can be'placed upon eitherside of the road-bed as desired. This can be done-either by removingtheupper section of the casing and reversing the parts or byinterchanging the arm n and the crank 16.

It is to be observed that the detector-bar is raised to its mostelevated position at the middle point of movement of the rotary parts.Thus at each limit of its movement it is at its lowest position-i. 6.,in such position that the switch cannot be'operated so long asa Wheel isover the-detector-bar.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The combination, with asuitable casing, of a lever fulcrumed in andprojecting into said casing at one of its ends, a cylinder having aspiral slot and journaled within said casing, said lever having aprojection at its inner end' engaging said slot, a signalcarryingspindle journaled in said casing, and a crank carried by said spindle,said crank and the outer end of said lever being contiguous to eachother and the one having a slot and the other a pin engaging said slot,substantially as described.

2. The combination, with asuitable casing comprising separable sections,ofa lever fulcrumed in and projecting into said casing at one ofitsends, a cylinder having a spiral slot and journaledin said casingbetween theseceasi tions thereof, the inner end of said lever having aprojection engaging said slot, a signalcarrying spindle jou rnaled insaid casing, and a crank carried by said spindle, said crank and theouter end of said lever being contiguons to each other and the onehaving a slot and the other a pin engaging said slot, substantially asdescribed.

3. In a switch-operating mechanism, the combination, with a leveradapted to be opera tively connected to the switch, of a casingcomprising separable sections disposed the one above the other, saidlever being fulcrumed in one of said sections and project ing into thecasing at one end, a cylinder having trnnnions and inclosed in saidcasing, the trunnions of said cylinder being journaled in the casingbetween the sections thereof and said cylinder and the inner end of thelever having a slot-and-pin connection between them, a crank andoperating-arm removably carried by the respective trunnions,said crankbeing adapted to be connected to a detectorbar or other similar part, asignal-carrying spindle journaled in a portion of said casing,

and another crank carried by said spindle, said crank and the outer endof the lever being contiguous to each other and the one having a slotand the other a pin engaging said slot and said outer end of the leverbeing adapted to be connected to the switch, substantially as described.

4. In a switch-operating mechanism, the combination of a casingcomprising separable sections disposed the one above the other, asuitably-fulcrnmed lever projecting into said casing, one of the wallsof said casing having a slot for said lever, a slide covering said slotand movable with the lever, and means for operating said lever inclosedin said casing,

the upper casing-section having a flange overlapping the joint betweensaid sections, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this22d day of November, 1900.
